Parallel abstract (English)

Electric motors without frequency converters have almost no additional features except being
able to be turned on and off. Electric motors are not easy to be operated with within certain
modes of operation. Preset conditions are to be set up upon the conduction of a thorough
analysis. A core thing is to have sound theoretical background about electric motors and
frequency dividers. For the purpose of this paper, Siemens Sinamics G120C was used.
Preparations were necessary; they lasted for a few months and consisted of learning about
electric motors and frequency dividers. The next step was to come to company TEO – Belišće
and sequentially parameterize with their assistance. Entering the specifications of an electric
motor in the program, ignition and extinguishing were enabled. Gradual ignition and
extinguishing (10 seconds) were also enabled. Furthermore, providing a safety stop was of
utmost importance. Parameterizing was finished and it was necessary to see where a frequency
divider can be used with some additional functions. The example shown in the company was a
machine which test properties of earth where a construction will be built.
